Abstract

The present invention relates to bicycle technology, and is especially one kind of portable folding bicycle. The portable folding bicycle has one crossbeam structure of foldable parallelogram mechanism, one front telescopic upper vertical rod with handlebar inserted into and fastened in the front lower vertical rod; one back telescopic upper vertical rod with saddle inserted into and fastened in the back lower vertical rod, one front fork and one back fork supported separately on the front and the back wheel; one front connecting board, one front upper crossbeam, one front lower crossbeam and one side link rod constituting the front quadrangle; one back connecting board, one back upper crossbeam, one back lower crossbeam and one side link rod constituting the back quadrangle; one upper link rod slide, one lower link rod and one locking mechanism to connect the front part and the back part of the bicycle.

Description

Portable folding bicycle

Technical field:

The invention belongs to and relate to technical field of bicycles, definite a kind of portable folding bicycle of saying so.

Background technology:

Make a general survey of various in the market folding bicycles, volume after folding is huge, and inconvenience is collected, put and carry, and moves difficulty, and this is to Ms, child, old man and weakling, and its difficulty is more obvious.Though the folding back of some folding bicycle has volume less, characteristics such as weight is lighter, but owing to the inventor pursues too that these characteristics have been ignored practicality and comfort level when using, make the practicality of these folded bicycles and comfort level even safety all have a greatly reduced quality, become near big child Che Liao, so be necessary to carry out in this respect in-depth study and exploitation.

Summary of the invention:

The objective of the invention is to: solve the weak point of above-mentioned like product, make behind the bicycle folding one to want volume little, two want weight lighter, and three will be convenient for carrying and collect, and four want practical, comfortable and safe.

The technical solution adopted for the present invention to solve the technical problems is: the present invention is characterised in that beam structure adopts the fold mechanism of variable parallelogram mode, whole car can be folded up to the centre from front and back, the related handlebar of front stretching upper pright stanchion inserts in the preceding vertical rod down, extended or indentation, fastening with catch gear, the back related vehicle seat of flexible upper pright stanchion inserts the back down in the vertical rod, extended or indentation, fastening with catch gear, the structure of whole car and weight are supported on the forward and backward wheel by front fork and back vent; Quadrangle before preceding connecting panel, preceding entablatrance, preceding cross sill and side connecting rod are formed, back connecting panel, back entablatrance, back cross sill and another piece side connecting rod are formed the back quadrangle, and couple together before and after making whole car by boxed rod slide plate, lower link and catch gear, forms geometry unmodified body structures; Be in rideable state this moment, when the catch gear of opening locking boxed rod slide plate, grasp the boxed rod slide plate when being pulled upwardly, but two parallelogram of front and back just become variant how much, before the drive, each parts of aftercarriage are folding to the middle part of car, while axis slide block can drive axis and sprocket wheel slides backward, and under the restriction of axis strut, stop in position, again preceding, the catch gear of back vertical rod is opened, before the indentation, back upper pright stanchion, and open catch gear on the vehicle seat, and being folded down vehicle seat, whole car is just collapsible, be in this moment can collect or carrier state, folding back size is about 70*40*15CM, out can put into below the automotive seat or in the baggage container of aircraft, can put chair in building, doss, below desk or the desk.

The invention has the beneficial effects as follows: solve the weak point of like product, make bicycle folding after volume little, weight is lighter, is convenient for carrying and collects, and is practical, comfortable and safe.

Description of drawings:

Fig. 1 is a structural representation sketch of the present invention.

Fig. 2 is the folding back of the present invention simplified schematic diagram.

Each numeral is expressed as follows respectively as shown in the figure: 1, handlebar 2, front stretching upper pright stanchion 3, catch gear 4, preceding vertical rod 5 down, pipe 6 before the vehicle frame, wheel 7, preceding connecting panel 8, preceding entablatrance 9, preceding cross sill 10, front fork 11, boxed rod slide plate 12, side connecting rod 13, lower link 14, axis slide block 15, pedal 16, axis strut 17, chain 18, back vent 19, back cross sill 20, back entablatrance 21, back connecting panel 22, back vertical rod 23 down, the flexible upper pright stanchion 24 in back, vehicle seat.

Specific embodiment:

The present invention is characterised in that beam structure adopts the fold mechanism of variable parallelogram mode, whole car can be folded up to the centre from front and back, front stretching upper pright stanchion 2 related handlebars 1 insert in the preceding vertical rod 4 down, extended or indentation, fastening with catch gear 3, the flexible upper pright stanchion 23 related vehicle seats 24 in back insert the back down in the vertical rod 22, extended or indentation, fastening with catch gear 3, the structure of whole car and weight are supported on the forward and backward wheel 6 by front fork 10 and back vent 18; Quadrangle before preceding connecting panel 7, preceding entablatrance 8, preceding cross sill 9 and side connecting rod 12 are formed, back connecting panel 21, back entablatrance 20, back cross sill 19 and another piece side connecting rod are formed the back quadrangle, and couple together before and after making whole car by boxed rod slide plate 11, lower link 13 and catch gear 3, forms geometry unmodified body structures; Be in rideable state this moment, when the catch gear 3 of opening locking boxed rod slide plate 11, grasp boxed rod slide plate 11 when being pulled upwardly, but two parallelogram of front and back just become variant how much, before the drive, each parts of aftercarriage are folding to the middle part of car, while axis slide block can drive axis and sprocket wheel slides backward, and under the restriction of axis strut 16, stop in position, again preceding, back vertical rod 4 and 22 catch gear 3 are opened, before the indentation, back upper pright stanchion 2 and 23, and open catch gear 3 on the vehicle seat 24, and being folded down vehicle seat 24, whole car is just collapsible, be in this moment can collect or carrier state, folding back size is about 70*40*15CM, out can put into below the automotive seat or in the baggage container of aircraft, can put chair in building, doss, below desk or the desk.

The present invention can solve the weak point of like product, make bicycle folding after volume little, weight is lighter, is convenient for carrying and collects, and is practical, comfortable and safe.
